钵水母类的早期个体发育涉及身体形态和功能的转变，影响捕食者的推进和摄食策略。我们采用高速摄像，数字粒子图像测速（DPIV），和染料可视化技术，以评估在个体发育过程中的根口水母Lychnorhiza lucerna Haeckel，1880年（Scyphozoa，Racostomeae）的游泳和进食机制的改变。在早期个体发育过程中，蝶状口唇沿着口臂沿着发育成复杂的过滤结构。粘性环境（雷诺数
The early ontogeny of scyphomedusae involves morphological and functional transitions in body plans that affect the predators' propulsive and feeding strategies. We applied highspeed videography, digital particle image velocimetry (DPIV), and dye visualization techniques to evaluate alterations in swimming and feeding mechanisms during ontogeny of the rhizostome medusa Lychnorhiza lucerna Haeckel, 1880 (Scyphozoa, Rhizostomeae). During early ontogeny, the ephyral mouth lips develop into complex filtering structures along the oral arms. The viscous environments (Reynolds number
